Inform communities of the release by default of ORES good faith and damaging UI, prior of the release of the new RC filters as a Beta feature.

• It won’t effect people that much, except for the red “r”, which can make it black locally if they want to
• There will be a new preference to turn on highlighting on the non-RC pages that have ORES (Watchlist and Contributions).
• If you had the highlighting before, you will have it, if you haven’t enabled the Beta feature, you don’t have the highlighting.
  
  Steps:
• Draft a message to be posted on the concerned wikis as defined on T146972
• Send a message one week before the release and the day before that change on places where to post that message (village pumps - technical ones, patrollers boards...)
